predator 212 hemi idling and reving stalling

[braggestkey]

so i have a predator 212 hemi with a GREHUA PWK 24mm carb and idles fine on choke but when switched to run it revs up pretty high then almost dies and to keep it running it needs to be reved up but will not steady idle on run I've tried adjusting idle screw as well as fuel air mixture screw so if someone has an idea of what could be happening not sure if i need more air or fuel but the gas tank and valve cover are both vented properly so no issue there but if someone could help me that would be greatly appreciated

It’s too lean and/or you have an air leak. Spray WD-40 around the intake while it’s running and see it it affects the way it runs. If it does, fix the air leak. If it doesn’t, you need bigger jets.
